Answer :

[tex]\huge\text{Hey there!}[/tex]

[tex]\mathsf{\dfrac{3}{4}\times\dfrac{2}{5} - \dfrac{1}{5}\times\dfrac{1}{4}}[/tex]

[tex]\mathsf{= \dfrac{3\times2}{4\times5} - \dfrac{1\times1}{5\times4}}[/tex]

[tex]\mathsf{= \dfrac{6}{20} - \dfrac{1}{20}}[/tex]

[tex]\mathsf{= \dfrac{6 - 1}{20 - 0}}[/tex]

[tex]\mathsf{= \dfrac{5}{20}}[/tex]

[tex]\mathsf{= \dfrac{5\div5}{20\div5}}[/tex]

[tex]\mathsf{= \dfrac{1}{4}}[/tex]

[tex]\huge\text{Therefore, your answer should be: \boxed{\mathsf{\dfrac{1}{4}}}}\huge\checkmark[/tex]

[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
